HARDWARE SETUP

3
Step-1
Solder 2 wires and connect the S12ZVM-EWP with DC power supply. Set the voltage to
12V and the current limit to 7.0A; If want to test PWM/LIN, solder the orange wire.
PWM/LIN
Do not turn power on this moment!

4
Step-2
•Solder 3 wires and connect to the 3 phase water pump or other PMSMs.

5
Step-3
Connect PE Multilink debugger to BDM port (H1) onboard and PC. If you want to
connect FreeMASTER by SCI, please solder H1 port 3 wires on the other side of
PCB, connect TX, RX and GND to a SCI-to-USB tool.

6
•Turn the power supply on
•Follow the QSG, get the S12ZVML-EWP software package, change the MCAT
parameters to compatible with your PMSM
•Download the firmware to the board and using FreeMASTER to control your PMSM
•If you have issues about the firmware download or debug, please following
software user manual for more information
Step-4

HARDWARE CONSIDERATION

8
Heat Dissipation
•If water pump or PMSM running with big load, S12ZVM and MOSFETs will produce
heat. So be careful.
•If heat accumulate and very hot, using some heat sink or cooling fan can help.

9
Motor running direction
If motor running in the wrong direction, 2 methods can help:
•Change the 2 wires of motor phases
•Set the motor speed to the minus speed
